Why would anyone swap fuel injectors to begin with when to swap the coil and the plug first that would be the easiest way to go about it you will never ever swap a few injector first because then you’re putting yourself at risk of breaking an injector or a fuel line and or both ripping the seal. You would never start with a fuel injector. You always start with a spark, plug and or coil and if you that doesn’t solve it, then you move the injectors who directly goes to a few injector when they have a misfire that’s crazy to assume it’s an injector right away before testing the plugs and coils
I have an Excursion over 320k miles on it with the original fuel injectors. What’s the recommendation to changing these as part of regular maintenance?
I have a 2020 mustang and had the po303 code for misfire and I replaced the spark plug, coil and fuel pressure sensor but it’s still misfiring, could it be the fuel injector?
Wow! You are very well versed and smart! Can feul injectors cause intermittent stumbling and transient rough idle. I've been replacing just about everything, including catalytic converter (oem), for the last 15 years on my 2005 chevy express 1500,, to no avail. Also,, sometimes very rough starting and other times very easy. I'm out of ideas and money,, Please help 😢 - 😊
@@8020Media my car was fixed but now I smell gas when I start the car. Here's how the accident happened... I was on a residential street turning right into a driveway. Then a car hits me on the right because the driver tried to pass me on the right as I was making a right into the driveway at about 5 mph. And the other driver was probably going 40 mph. Nuts huh! Good thing for dash cam ^.^
KC - Glad to hear you're okay! Yes, always great to have a dashcam. Don't think this is a fuel injector issue. What other symptoms are you experiencing?
14 maxima here, I hit a deer on my passenger side. I would check everything around the radiator and everything around your AC compressor along with your AC lines. I had a cracked radiator hose and a crack near the radiator cap along with a slight crack in the high side hose of the AC…and didn’t discover any of it until months after the car was “fixed”. Your fuel injectors should be the least of your concerns lol
I have a question, I have a 2021 Sorento. I’ve had two fuel injectors replaced and the fuel pump replaced. My car has 50k miles on it, why would I be having such issues? The dealership isn’t being very helpful. Seems excessive to me.
I am having the same issue right now with the customers car, they say it’s a common issue with Kia‘s and Santa Fe, the fuel injectors, or possibly the O-rings on the fuel injectors they’re just replacing the injectors which end up coming coming with the seals I think it’s a seal issue
I have endeavored to change my fuel injectors in my 2000 Corolla. It has been a wild ride with the injectors leaking due to the injector o-rings tearing or getting chewed up. Thankfully, I have a lot of spares and I have gotten better at inserting and lubricating them. I finally managed to get the injectors to stop leaking but then I was hit with numerous low-300 misfire codes plus P0172 (running too rich). I read up on the misfires and the lower seals needed to be lubricated so I used Vaseline. No more 300 codes but I still have P0172. LTFT goes down to -26%, which is quite ironic considering I've been dealing with P0171 for the longest time. The car idles softly like it may sputter out when I drive slowly or stop I assume this rich condition is from all of the excess fuel that went into the cylinders/engine from dealing with the recurring leaks and lifting the rail up and back so much and gas going into the port holes. It's not like it was a water hose or anything but still a decent amount over time as I couldn't run the engine with the injectors leaking. Will this rich fuel condition work itself out with the engine drying on its own the more I drive or what can I do?
@@8020Media Thank you for the link. It turned out to be the fuel injectors. The reason I was getting P0172 was that the new injectors, which were bought on eBay, were apparently not flow matched. I was told to put the originals back in so I used a rebuild kit and cleaned the insides with MAF sensor cleaner after removing the old basket filters. I had numerous misfire codes after doing this but after disconnecting and reconnecting the battery the codes disappeared and I could see that LTFT now only goes up to 19.5%. This may seem like a lot but it was reaching up to 39% prior with P0171 always coming on. I was able to green light the various systems and get it smogged today. For THREE years I dealt with this perpetual code coming on and I couldn't figure out the culprit. I had changed the fuel cap, PCV valve, MAF sensor, 02 sensor, ECU, checked for vacuum leaks, and redid the manifold intake gasket all to no avail.
Hello, and thank you for the informative video. I'm hoping you can give me some insight into a problem I am having with my 2015 ford flex limited. For the last couple of months my flex has developed a stutter between 25 to 45 miles mph. I can see the tach jumping during this stutter. The problem is I am getting zero fault codes. I assumed maybe clogged or bad injector. I have run several tanks of premium fuel and added techron fuel system cleaner to it as well. No changes at all. Am I incorrect in my assumption or is it still a possible injector problem and how would I diagnose which injector. At idle no miss is detectable. Thanks for any help that you can provide.
